[Bugfix] Group member can not mint

related #171

Description

This PR fixes a case when the pathfinder does not find a correct path from a group member to a group:

In this case, when there is a direct relationship between the user and the group, the expected user to be used in the group mint method is the transaction sender (safe address)
